According to docs, obtained by TMZ, the judge ruled Norma Gibson can't expect Tyrese to reimburse her for babysitters to watch their 11-year-old daughter, Shayla ... if Norma's running "non-work errands" or running her household.

In the docs, the judge lays out what qualifies as work activities for Norma -- including developing her life coaching biz, working on her book or pursuing her art. The court says if she requires childcare while doing any of those things ... she can put that on Tyrese's tab.

We don’t really need an up to the minute update on this clown’s custody issues. His child support nonsense shouldn’t be the only thing he’s making headlines for. What happened to that billion dollar business meeting in the Middle East he was supposed to be orchestrating the last year? This guy needs to wake up and realize his career is gone. So does Snitch.
